Check out this review on Amazon from one happy user:

After the negative comment from someone I decided to take a chance on this product anyway. So glad I did! It works perfect for viewing and recording from my Sony A65 hdmi output. I can now see live camera view in Full Screen on my older Dell inspiron 1525. I can setup a photo with the Sony A65’s with the camera hdmi output and see it on my laptops much larger screen. Final product view before and after the shot is awesome! Video mode in extreme high res is also no problem… It can also record the entire real Estate photo shoot’s stills and video with out having to switch back and forth. Best $149.00 investment for your camera to laptop interface available anywhere! I highly recommend this product!
